Automotive Battery Analyser

The Jansicotek KW650 tests 6V and 12V lead-acid batteries rated from 100 to 2000 CCA. It covers regular flooded, AGM flat plate, AGM spiral and gel types. The unit works in-vehicle or on the bench without removing the battery. It is aimed at DIY owners and professional technicians who need quick health and charge-state readings.

Upgrade from Basic Load Testers

Unlike simple voltage-only checkers, the KW650 reads cold cranking amps, internal resistance, state of health and state of charge. It also runs starter-motor and alternator-charging tests. The jump is worth it when you must diagnose no-start faults, verify alternator output or confirm battery replacement before buying.

Limits of the CCA Test Standard

Results follow CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB reference tables built into the firmware. Accuracy is quoted at 99.5 percent against a Midtronics reference. The tester cannot assess lithium-ion chemistries, high-voltage EV packs or batteries outside the 100-2000 CCA window.
